In the middle and late stages of peanuts (from flowering to pod-forming stage), foliar spray application has a good effect on promoting peanut pods with large grain filling, increasing yield and income, and improving pod quality. The spraying method of five kinds of foliar fertilizers is now introduced.
1. Aqueous urea solution. The soil is sandy, the soil is thin, the base fertilizer is insufficient, the plant is short, the growth is weak, and the leaves are yellowed. During the flowering to the pod-forming stage, the 0.7%-1% aqueous urea solution is sprayed on the leaves to increase the dry matter accumulation. It has a good effect and the average yield is increased by more than 10%. Miaowang Zhujian has a field with a strong tendency to grow, and it is not necessary to spray urea.
2. Superphosphate water leaching solution. On the basis of the basic application or the application of phosphate fertilizer, spraying 1.5%-2% of the superphosphate calcium water leaching solution (immersed for 14-16 hours) twice during the flowering period and the lower needle-podding period can enhance flowering and knotting. The performance of the pods increases the yield of peanuts by 12%-18%.
3, grass wood gray water leaching solution. The plant ash is a farmer's potash, with an average potassium content of 5%-6% or more, of which more than 90% is water-soluble potassium carbonate. During the period from the beginning of peanut pod formation to the pod expansion period, spraying 5% concentration of grass ash water leaching solution twice, combined with bacon, can increase peanut yield by more than 20%.
4. An aqueous solution of potassium dihydrogen phosphate. Potassium dihydrogen phosphate is a high-efficiency compound fertilizer containing phosphorus and potassium. During the period from the flowering stage of the peanut to the pod expansion period, the leaf surface is sprayed with 0.3% potassium dihydrogen phosphate twice. According to the test, in the Peanut Wangchangtian, the flowering period of potassium dihydrogen phosphate was sprayed once, which was 19 kg more than the unsprayed per mu. The flowering period and the pod expansion period were sprayed once, and the per pod yield increased by 28.5 kg.
5. Boron fertilizer aqueous solution. Boron promotes the development of peanut flowers and enhances fertilization. Less boron-poor pods and more empty shell fruits. Spraying 0.2% boric acid or 0.3% borax aqueous solution on the leaf surface from flowering to pod-forming period, the average number of results per plant increased by 1.4, the fruit filling rate increased by 4.3%, and the fruit weight increased by 3.3 grams per acre. Increased production of 26 kg of pods.
